Unfortunately for me I had these exact same issues with the additional heads and with the Weeping Angel, so for me it seems to be a standard thing now. It's already starting to grow a bit wearying, really.
Honestly, at this point I'm not even sure if I'll pre-order the next release. I'll undoubtedly almost definitely still buy it, but why give them my money so far ahead of time, if that support and loyalty doesn't go both ways? Especially now that they have a US distribution deal in place again. I mean I have a ton of stuff already pre-ordered with them, so they have plenty of opportunity to win me back around and change my mind, but unless the next incentive is a must have I might take my future purchases via another route instead. Seriously considering it, anyway.
